出门在外也不愁The Orbit of the Moon around the Sun is Convex!
The Orbit of the Moon around the Sun is Convex!
What does the orbit of the Moon around the Sun look like? Most people, even
almost all mathematicians I've asked this question, tend to believe that it
will have loops and look something like the picture below.
In fact it looks like this picture!
It is not a circle, but is close to a 12-gon with rounded corners. It
is locally convex in the sense that it has no loops and the curvature never
changes sign. (To be precise, it is more like a 13-gon, since we have to consider
the sidereal month of 27.32 days instead of the synodic month of 29.54 days,
and 365.25/27.32 = 13.37.)
There are several ways to see this. Since the eccentricities are small,
we can assume that the orbits of the Earth around the Sun and the
Moon around the Earth are both circles. The radius of the Earth's
orbit is about 400 times the radius of the Moon's orbit.
The Moon makes about 13 revolutions in the course of a year. The speed
of the Earth around the Sun is about 30 times the speed of the Moon
around the Earth. That means that the
speed of the Moon around
the Sun will vary between about 103% and 97% of the speed of the
Earth around the Sun. In particular, the speed of the Moon around
the Sun will never be negative, so the Moon will never loop backwards.
I like to visualize this as follows. Imagine you're driving on a circular race
track. You overtake a car on the right, and immediately slow down and go into
the left lane. When the other car passes you, you speed up and overtake on the
right again. You will then be making circles around the other car, but when
seen from above, both of you are driving forward all the time and your path
will be convex.
Another approach is to compute the gravitational forces involved.
It can be shown that the Sun's pull on the Moon is about twice the Earth's pull on the Moon. It follows that the Moon's orbit is primarily determined by the gravitation pull from the Sun, so the orbit of the Earth will always curve towards the Sun.
Here is a sketch of the details.
(G MassSun MassMoon/Distance(Sun-Moon)^2)/(G MassEarth MassMoon/Distance(Earth-Moon)^2) =
(MassSun/MassEarth) (Distance(Earth-Moon)/Distance(Sun-Moon))^2.
But Distance(Sun-Moon) is close to Distance(Sun-Earth), and Distance(Earth-Moon)/Distance(Sun-Earth) is 1/390 while
MassSun/MassEarth = 3.34X10^5, so we get 2.20.
You may also want to remember that it is the barycenter of the Earth-Moon system that moves
in an ellipse around the Sun, and that the orbits of both the Earth and the
Moon are perturbations of this ellipse.
by Erich Neuwirth is very nice,
but you must first get the
“The Sun, the Moon, and Convexity” by Noah Samuel Brannen in The College Mathematics Journal v. 32, 268-272 (2001) is excellent,
but also look at “Why the Moon's Orbit is Convex” by Laurent Hodges in The College Mathematics Journal v. 33, 169-170 (2002).
“Mad about Physics” by Jargodzki and Potter also discusses this problem.
The National Maritime Museum mentions this on their fact file about
but has a bad picture on their fact file about
If we assume that the ellipses are circles, the radius of the Moon's orbit is 1, the radius of the Earth's orbit is d,
and that the Moon makes p revolutions while the Earth makes one, then we get curves of the form (d cos(t) + cos(p t), d sin(t) + sin(p t)).
Above I used d=400 and p=13, but if we had changed the parameters, we could have gotten pictures like these.
It turns out that we loops when d & p, a wiggly path when p & d & p^2 and a convex path if p^2 & d.
For details, see the article by Brannen.

英语作业中遇到困难,1.Which is ________to the earth,the moon or the sun?A near B nearer C nearest D the nearest2.Of these children ,Danny is____________(thin)3 They will come back at ten o'clock (改写同义句)They __________come back ________ten o'clock
1.Which is ________to the earth,the moon or the sun?A near B nearer C nearest D the nearest2.Of these children ,Danny is____________(thin)3 They will come back at ten o'clock (改写同义句)They __________come back ________ten o'clock
1.Which is （B nearer ）to the earth,the moon or the sun?月球和太阳哪一个离地球更近?两者作比较,用比较级.2.Of these children ,Danny is (the thinnest).丹尼是这些孩子当中最瘦的.of短语是比较的范围,用最高级.孩子的数量在三个以上.3 They will come back at ten o'clock (改写同义句)They （won't）come back （until）ten o'clock.他们要到十点才回来.not ...until,直到某时才做.
B、thinnest、won't、until
MOON ， SUN） 相比用比较级。2 the thinnest 在所有的孩子中，DANNY 是最瘦的。3
won't , until
注：not ... until ... 直到……才……加油！不明白再问！如果帮到你，请采纳，谢谢！2 题答案
the thinnest 在所有的孩子中，D...
形容词最高级前要加THE不可以
B 比较级 月亮和太阳的比较thinest 最高级 在这些孩子当中，丹尼是最瘦的won't until 直到……才……
thin3这个我不知道啊。选为满意答案啊
1. B2. the thinest3. are going to
B 因为提问者只提出两个物体的比较 所以哪个更近？the thinnest 在这些孩子里 Danny是最瘦的 因为是与许多人的比较are going to around/at 表将来时可以用be going to
B 两个比较级就行了2
the thinnest；按多人想3
两个之间做比较2 the thinnest
两个以上的做比较，用最高级。 thin-thinner比较级-thinnest最高级3 are going to
他们下面说的是错的1：地球，月亮，太阳三者比较用最高级，而不是比较级。而最高级前要加the，所以选D2：these children 也是最高级 ，不要忘记加the，且thin要双写n,所以答案是：the thinnest3：won't until not until的用法。}
